I've tried Robitussin.
I've tried Zyrtec.
I've tried cough drops, humidifiers, rest, lots of liquids...
I've though about going to the doctor and rejected that idea because I've lost faith in the medical community.
I'm thinking that there might be one last trick to try before I give up:
I'll let you know whether or not it works.
But I won't share... : )
